A small company recordkeeping routine should be boring: raise sales invoices promptly, capture receipts as you spend, reconcile the bank feed, keep payroll and VAT documents with the month they relate to, and review open questions every month. The aim is simple evidence for your accounts and tax returns from day one.
Carr Accounting Studio helps UK founders keep the records clean enough for HMRC, Companies House and to help you make better decisions, without asking the founder to become a bookkeeper.
What records does a small company need to keep?
A limited company needs records that explain the figures in its accounts and tax returns. In practice, that means keeping the story behind the money:
| Record type | What it proves | Founder habit |
|---|---|---|
| Sales invoices and income records | What the company earned and who paid | Raise invoices from one place and match cash receipts to them |
| Purchase invoices and receipts | What the company spent and why it was business-related | Capture the document when the cost is incurred |
| Bank and card statements | What actually moved through the accounts | Save statements and reconcile the bank feed |
| Payroll records | Salary, deductions and payments where PAYE applies | Keep payslips, reports and payment evidence together |
| VAT records | VAT charged, VAT reclaimed and return support where registered | Keep VAT evidence with the relevant month or quarter |
| Director and shareholder records | Money taken out, loans, dividends and capital | Keep approvals and workings with the accounting records |
| Accountant queries | Gaps, explanations and decisions | Answer while the transaction is still familiar |
The exact pack depends on the business. A SaaS founder, e-commerce store and service company can all need different evidence, even when they use the same accounting software.
How often should a founder update the records?
Use a monthly rhythm as the minimum. For a simple company, one properly protected monthly session can keep the records clean. For a busier company with several bank accounts, card processors or sales channels, weekly checks will likely save time because the query list stays shorter.
The routine matters more than the tool. A tidy spreadsheet updated every week is better than expensive software ignored until the tax return is due. That said, a limited company usually becomes easier to run through proper accounting software once bank feeds, invoices, VAT or payroll enter the picture.
What should happen every week?
A weekly check is a light pass:
- Check bank feeds are running.
- Upload new receipts and bills.
- Raise any sales invoices that are due to go out.
- Match obvious bank receipts to sales invoices.
- Flag anything unexplained.
- Check payment processors for payouts, fees or unmatched sales.
This is the habit that stops records turning into a memory test. It also keeps personal and company spending separate, which protects the quality of the accounts.
What should happen every month?
The monthly review is where the records become usable:
- Reconcile every bank and payment account to the statement.
- Clear the receipt and bill capture queue, including any duplicates or failed uploads.
- Review bills awaiting payment for duplicates or items already paid.
- Check unpaid sales invoices and unmatched cash receipts.
- Check VAT and PAYE control accounts where they apply.
- Put anything unresolved into a query list with a plain explanation.
- Save the statement and review note for the month.
If an accountant handles your bookkeeping, this monthly close is the work they should be able to evidence: what was reconciled, what was reviewed, what was queried and what remains open.
How should receipts, bills and bank statements be stored?
Store documents where they can be matched back to the transaction. A photo on a phone, a supplier email, a PDF invoice and a bank payment all need to connect.
For many founders, the cleanest route is:
- Sales invoices raised or imported into the ledger.
- Supplier bills and receipts uploaded through the accounting software or a capture app.
- Bank statements saved as PDF for each account each month.
- Payroll, VAT and tax documents saved with the period they relate to.
- One query list for anything the records do not explain.
Avoid running the company from screenshots, email searches and personal memory. Those may help in a pinch, but they are poor evidence when an accountant needs to prepare signed accounts or help you answer HMRC questions.
How does the routine change if you are VAT-registered or run payroll?
VAT and payroll add review points to the routine.
For VAT, the records need to support the return. That means invoices, receipts, VAT rates, overseas or import issues, and any items your accountant has asked you to flag. The bookkeeping should be ready before the VAT return is prepared.
For payroll, keep the payslips, payroll reports and payment evidence together. If you pay yourself as a director, agree the salary routine before payments start so the accounting records, payroll submissions and bank payments line up.
If you also trade as a sole trader or have property income outside the company, Making Tax Digital for Income Tax may require digital records and quarterly updates for that separate income source. The limited company's own records follow the company rules, but your personal recordkeeping routine may need to allow for both.
What should you give your accountant before year end?
Your accountant should be able to review the year from records that already explain the main movements. Before year end, aim to have:
- Reconciled bank and payment accounts.
- Sales invoices matched to money received.
- Receipts and bills attached to costs.
- Payroll records saved, if payroll applies.
- VAT return support saved, if VAT applies.
- Director payments, dividends and loan movements explained.
- A list of open questions rather than hidden gaps.
Good records make the year-end accounts cheaper to review, easier to sign and more useful to you. They also support the tax position if HMRC asks how a figure was reached.

Frequently asked questions
What records should a small limited company keep? Keep sales invoices, purchase invoices, receipts, bank statements, payroll records where relevant, VAT records where relevant, dividend and director-loan workings, and notes that explain unresolved transactions.
How often should a small company do bookkeeping? Monthly is a sensible floor. Weekly checks are useful where the company has several accounts, payment processors, sales channels, VAT deadlines or higher transaction volume.
Can I keep records in a spreadsheet? A spreadsheet can work for a very simple recordkeeping routine, but accounting software is usually better once bank feeds, VAT, payroll, sales invoices or accountant access matter.
Do I need to keep paper receipts? The evidence needs to be kept and readable. A reliable digital copy attached to the transaction is usually easier to manage than a folder of paper, but check before relying on any recordkeeping route for your own situation.
Does MTD for Income Tax apply to my limited company? MTD for Income Tax applies to sole-trader and property income. The limited company's own records follow the company rules, but MTD for Income Tax can still affect you personally if you have those income sources outside the company.
